Change the font search order to try Lucida Sans Unicode before Arial Unicode ...

Change the font search order to try Lucida Sans Unicode before Arial Unicode MS because the former is available
on Windows XP or later while the latter is only available with MS Office installed.

This is partly to make font-dependent layout test results 'invariant' with or without Arial Unicode MS installed.
Eventually, we may want to make those tests more robust against the font availability by removing some Unicode 
characters not commonly available.  

BUG=2304
TEST=pass the layout tests affected
